Title: Improvements in or relating to platinum- or palladium-containing catalysts
IPC: B01J31/16
Filed: 1952-09-10
Abstract: A platinum- or palladium-containing hydrocarbon conversion catalyst is prepared by impregnating a finely-divided carrier with a solution of a platinum or palladium compound, drying and mixing with a finely-divided solid diluent base free from platinum or palladium to produce a composite catalyst containing about 0.01-2 per cent by weight (preferably 0.1-1 per cent) of platinum or palladium.  The preferred diluent consists predominantly of alumina which may be promoted or stabilized with minor amounts of silica, boria, chromia, phosphoric anhydride, zirconia, thoria, magnesia, titania, zinc oxide, or halogen acids.  The carrier may consist of the same material, or of alumina promoted with oxides of calcium or potassium; other suitable carriers are silica, zirconia, titania, magnesia, thoria, zinc oxide, or activated carbon.  Alumina in the form of activated alumina or alpha alumina (corundum) may be used; activated alumina may be pre-dried at 200-1400 DEG  F. for 2-24 hours.  The carrier is mixed with an aqueous solution of chloroplatinic acid or palladium chloride to yield an intermediate concentrate containing 1-35 per cent platinum or palladium; the concentrate is dried and may be calcined and reduced before mixing with the diluent base; the final composite is dried at 100-700 DEG  F., calcined or reduced while heating slowly up to 900-1000 DEG  F., and formed into pills. Examples describe the preparation of catalysts in which platinum is associated with active alumina, alpha alumina, zinc aluminate, or activated titania.  The catalysts may be used in a hydroforming process at pressures of 50-300 lbs. per sq. in., and have high stability towards oxygen regeneration.

Abstract: 1,209,116. Television. ALBISWERK ZURICH A.-G. 15 May, 1968 [15 June, 1967], No. 23015/68. Heading H4F. In a television circuit arrangement for stabilizing the black level of a video signal, supplied from terminal E via an A.C. coupling 3, by means of a diode 4 and a reference potential UB, the anode of the diode is connected to the emitter of a first transistor 1 connected in an emitter followed configuration and having its base connected to the reference potential via a second diode 5 and the video signal supplied to the cathode of diode 4 is fed to the cathode-ray display tube 7 via a complementary transistor 2 and a D.C. coupled amplifier 9. With this arrangement the difference UD between the output reference potential A and the reference potential UB (derived from the common connection point of two identical D.C. voltage sources U1, U2) is equal to UBE2+U4 - UBE1 - U5, where UBE1 and UBE2 are the base emitters voltages of transistors 1 and 2 respectively and U4 and U5 are the forward voltages of diodes D4 and D5 respectively. Since the base emitter voltages of the transistors are of equal magnitude and likewise the forward voltage of the diodes, UD is therefore equal to zero and changes in the forward voltage of the diode 4 due to temperature effects are self compensating. When several of the circuits described are to be used simultaneously in different channels in the same device that portion of the circuit including transistor 1 may be common to all the channels.

Abstract: 959,037. Photographic print-out materials. HORIZONS Inc. June 26, 1961 [July 12,1960], No. 23029/61. Heading G2C. A photographic print-out material comprises a layer containing an organic halogen-containing compound which yields free-radicals on exposure to light, and a basic dye of the formula wherein R and R<SP>1</SP> are methyl, ethyl,n-propyl benzyl groups, R<SP>11</SP> is H or CN,d and n are 1 or 2, m is 1, 2 or 3 but the sum of n and m is not greater than 4, and Q completes a 5- or 6-membered heterocyclic nucleus. The materials yield coloured print-out images on exposure to light,which images may be intensified by heating at between 85-100C. Coloured reliefs may be formed by dissolving away the unexposed portions in an organic solvent such as ether,benzene or ethyl acetate. The exposed portions are soluble in water, and direct positive images can therefore be produced by dissolving away the exposed areas and then giving the unexposed areas remaining a uniform exposure to produce a coloured image. Since the exposed areas are hydrophilic and the non-exposed areas are hydrophobic, the invention may be used for producing lithographic printing plates. Thus, the composition may be applied to a hydrophilic support such as paper and the exposed areas washed away with water. The light-sensitive compositions may contain binders and also hydrocarbons such as eicosane which may be added in a solution of an organic solvent such as benzene'or acetone. In the examples, the organic halogen-containing compound is carbon tetrabromide and the dye is 2- or 4- (4-p-dimethylaminsphenyl-1, 3-butadienyl) quinoline, 2- or 4-p-dimethylamino-styryl-quinoline or 2-p -dimethylstyrylbenzthiazole The compositions may contain nitrocellulose or polystyrene as a binder. The image colours produced according to the invention may be converted into lakes by treatment with salts of copper, chromium, cobalt, aluminium, phosphotungstic acid or phosphomolybdic acid.
